Access project version within elixir application

Question

I have an elixir project with a defined version. How can I access this from within the running application.

in mix.exs

  def project do
    [app: :my_app

In recent versions of Elixir, the Application module now wraps this for you:

https://github.com/elixir-lang/elixir/blob/master/lib/elixir/lib/application.ex

Application.spec(:my_app, :vsn) |> to_string()

The Kernel.to_string() method is necessary as Application.spec/2 for the keys :vsn and :description return charlists. to_string() from the Kernel module converts them to a binary.
